Prefabricated FRP pipe-concrete-steel pipe combined column and construction method thereof
The invention provides a prefabricated FRP pipe-concrete-steel pipe composite column and correspondingly provides a construction method of the composite column. The combined column comprises at leasttwo combined column sections, each combined column section comprises an FRP pipe section located on the outer side, a steel pipe section located in the FRP pipe section and a concrete layer located between the FRP pipe section and the steel pipe section, and the two steel pipe sections of any two adjacent combined column sections are connected and fixed. The two concrete layers of every two adjacent combination column sections are fixed through reinforcing steel bars. By implementing the prefabricated combined pipe section and the similar columnar structure, complex concrete pouring does not need to be conducted on site, only the prefabricated combined pipe section needs to be connected through the built-in steel pipe section, the locally-embedded reinforcing steel bars and the reinforcingsteel bar sleeves, the construction speed is high, on-site construction is convenient, and operation is easy. The flange plates, the reinforcing steel bars and the reinforcing steel bar sleeves for connection can also serve as stiffening or reinforcing measures of the combined column, and the structural performance of the combined column is improved.
本发明提供了一种预制装配式FRP管‑混凝土‑钢管组合柱，并相应提供了该组合柱的建造方法。组合柱，包括至少两个组合柱节段，每个组合柱节段均包括位于外侧的FRP管节段、位于FRP管节段内的钢管节段以及位于FRP管节段和钢管节段之间的混凝土层，任意两个相邻的组合柱节段的两钢管节段之间连接固定，且相邻两个组合柱节段的两混凝土层之间通过钢筋固定。实施本发明及类似的柱状结构无需在现场进行复杂的混凝土浇筑，仅需将已预制的组合管节段通过自带的钢管节段、局部预埋的钢筋和钢筋套筒实现连接，建造速度快，现场施工方便，操作简单。连接用的法兰盘、钢筋和钢筋套筒还可以作为组合柱的加劲或加强措施，提高了组合柱的结构性能。
